Implement protocol upgrade for HTTP/2 enabled requests
Without ALPN/NPN (== without OpenSSL) we can negotiate HTTP/2 using the protocol upgrade procedure as described by RFC7540. Since there is no TLS handshake, after our http channel was connected we first send an 'augmented' HTTP/1.1 request - its header contains additional 'HTTP2-Settings' and 'Upgrade' (to 'h2c') fields. If we receive reponse 101 (switch protocol) we re-create a protocol handler and switch to HTTP/2. Task-number: QTBUG-50955 Change-Id: I36e9985e06ba76edaf7fdb22bb43770f8d593c61 Reviewed-by: Edward Welbourne <>
